There have been numerous kernel patches that prevent stealth, fin and rst scans for Linux and BSD. I'm not sure as to updates, but you can the old sources for linux kernel 2.4.16 and BSD 4.4 in the downloads section of www.badc0ded.com.

Applying this code to the latest kernel builds should not be too difficult a problem.
